When looking to replace parts or investigating materials used in the parts in your machinery, you may come across the term PTFE quite often. Understanding what this material is and its applications can help you discern if it is the best material for your applications, and further, what grade of the material is correct for your use.
PTFE: What is it?
PTFE is what most people associate with the material officially known as polytetrafluoroethylene. Polytetrafluoroethylene is a synthetic polymer made of two elements, which are carbon and fluorine. It is a fluoropolymer that is used in a wide variety of industrial applications. It is best known for its heat and stick-resistant properties.
PTFE Characteristics and Applications
PTFE is used in a variety of applications because it boasts some unique characteristics. In fact, the general public likely has PTFE in their home as a brand name many are aware of is Teflon.
The characteristics that make this material unique include but are not limited to:
- Heat resistance. This material has a melting point of 327°C so there are very few applications where it can be damaged by heat.
- Water-resistant. Polytetrafluoroethylene is resistant to water making it useful in a wide variety of applications.
- Chemically inert. PTFE is resistant to most corrosives.
- Non-stick. The coefficient of friction associated with PTFE is one of the lowest of any solids known. Meaning, virtually nothing will stick to it.
- High flexibility. Polytetrafluoroethylene is quite flexible even at low temperatures and can be applied to surfaces without losing its integrity.
There are many applications associated with PTFE. The grade of this material used will depend on the application:
